c.J.D|EBAoLD WHISTLING BALL Filed July 5, 1926 ingly the whistlingball is extremely sensitive, that is to say, it takes very little motion of the ball to start it whistling. l

When the ball is projected, air 1s drawn into the bellows and in passing through the openings of the whistle-causes a whistlingA sound. Vhen thel ball recoils, the sprin closes the bellows and passes airthroug the whistle in the opposite direction to causeV a `further whistling sound.

I have found that by making the opening 5` comparatively large in respect to the size of the string, I obtain a much lbetter `whistlingfeiect than if said `opening were small as apparently, it is desirable that the air be free to enter and escape quickly when the bellows is expanding and contracting.

By making the bellows flexible `,and the opening 5 comparatively large and suspending the ball from the'bellows, the bellows and ball are given free movement and there is no possibility of any of the parts binding or being injured in anyway. Y i

\ I am aware that whistles have been heretofore used in connection with balls but in such the structure is so complicated and costly that the device cannot be marketed at a 'reasonable price and further the working parts are of such a rigid nature that freeness of movement is not permitted and the device is not sensitive andfurther there L is every possibility of the working parts l getting out ofV order.

` What I claim as my invention is l `1. In combination, a hollowball having opposing endopenings therein, an` annular discsurroundingione ofthe openings and secured to the ball, a whistle carried by the disc and covering said latter opening, an

lows in a collapsed position upon the ball being suspended by thestring.`

"2. In combination, a hollow ballformed `from upper and lower sections and having opposing openings in the upperand lower ends thereof an annular disc within and secured'to the lower endV of the ball and surrounding the loweropening, a whistle inserted within the disc and covering the latter opening, an upper disc opposing the` former annular disc, a flexible bellows forming material connecting therdiscs, an elastic string connected centrally to the' upper disc and passing outwardly through the upper end opening in the ball,"said latter end opening beingconsiderably larger than the string and a spring within the bellows and having one end secured to the whistle4 and the other to the upper disc, said spring beingdesigned to suspend theweight of the ball whilst maintaining the Vbellows normally in a collapsed position.
